Yep, more than likely toxins. I don't know of anything you can do to stop them...make sure you drink plenty of water to keep toxins flushing out of your system and as the cleanse progresses they should subside.

Did you know you store emotions in your liver? So, it just makes sense if you flush your liver , you will flush out all of your negative feelings.

Good luck and good health!

Hi Melissa...have you found a common theme in your nightmares while cleansing? They could be telling you something about what emotions/fears you're trying to release. As you are cleaning out your physical self, you're also cleaning out your emotional/spiritual self. If you write them down with the intent of finding something that you need to release, the 'a-ha!' experience will probably make the nightmares go away, as you will have 'gotten' it!

It's best if you can interpret them yourself...but if you need some help...here are some excellent (not superstitious and ridiculous!) on-line dream dictionaries:
